Document Summary

Joints are the articulations (sites) where two bones meet, giving our skeleton mobility and hold our skeleton together. Joints are the weakest part of the skeleton, however their structure resists various forces that threaten to force them out of alignment. In fibrous joints, the bones are connected by fibrous (collagen) connective tissue. There is no joint cavity present, which allows very little to no movement at this joint (depends on length of connective tissue). Sutures: seams only found in between bones of the skull. Overlapping/interlocking of wavy edges with the junction filled by a minimal amount of short connective tissue. Syndesmosis: bones are connected by a cord (ligament) or a sheet (interosseous membrane) of fibrous connective tissue. Slight to considerable movement possible depending on length of connective tissue. Bones joined by fibrous connective tissue (short periodontal ligament) Gomphoses: peg-in-socket connections (ie. tooth in bony socket) a) b) c) a) b) In cartilaginous joints, the bones are connected by cartilage.
